Inheritance

Architecture & LLD Preview

Inheritance

Mechanism where a new class is derived from an existing class to reuse code.

Inheritance allows a 'is-a' relationship between classes, enabling code reuse.

Core Design Challenge

"How do we avoid duplicating code across similar types of objects?"

What You'll Learn:

  • Encapsulation: hiding internal data and exposing interface methods
  • Abstraction: simplifying complex operations behind clean facades
  • Inheritance: promoting code reusability via superclass relationships
  • Polymorphism: executing dynamic implementations via shared interfaces
